Our Conductivity Sensor Product Line
Kainafu manufactures two conductivity sensor models to cover the full range of industrial and environmental applications:
KNF-102Pro — Conductivity / TDS / Salinity Sensor
A two-electrode graphite conductivity sensor designed for straightforward installation in pipelines or submerged deployments. Simultaneously measures conductivity, TDS, salinity, and temperature from a single probe.
| Specification | Value |
|---|---|
| Conductivity range | 0–600,000 μS/cm / 0.1–100 mS/cm |
| TDS range | 0–9,999 ppm |
| Salinity range | 0–100 ppt |
| Accuracy | <2.5% F.S. |
| Temperature range | 0–60°C / ±0.5°C |
| Protection | IP68 (6 bar / 50 m) |
| Output | RS-485, Modbus RTU |
| Power supply | 5–30 VDC |

KNF-102HPRO — High-Accuracy Conductivity / Salinity Sensor (Seawater)
A four-electrode graphite sensor supporting the International Salinity Scale (0–50 PSU) — designed for seawater, brine, and high-conductivity industrial process water monitoring.
| Specification | Value |
|---|---|
| Conductivity range | 100–600,000 μS/cm / 0.1–500 mS/cm |
| Salinity accuracy | <0.5 PSU (International Standard Seawater) |
| Accuracy | <1.5% F.S. or 2% of reading |
| Protection | IP68 (6 bar / 50 m) |
| Output | RS-485, Modbus RTU |
Both models support pipeline and submersible installation, with RS-485 remote calibration and parameter setting — no need to retrieve the sensor from the water to adjust settings.
Why Customers Choose Kainafu as Their Sensor Manufacturer
Factory-direct supply — No distributor margin. You pay the manufacturing price.
Full in-house R&D — Our engineers developed every sensor in our range. When you have a technical question, you speak directly to the people who designed the product.
OEM and customization — Cable length, measurement range, housing material (standard engineering plastic or 316L stainless steel or titanium alloy), communication protocol, and connector type can all be customized for volume orders.
Verified quality — ISO 9001 manufacturing processes, CMA-certified measurement accuracy, and full calibration records shipped with every unit.
Complete product ecosystem — Conductivity sensors integrate directly with our KNF-300 series controllers, KNF-400 series monitoring systems, and the Kainafu cloud platform — giving you a single supplier for the entire monitoring chain.
